To all whom it may concern.-

Be it known that l; FELIX QDo't: a resident of the city of izvmucket, in the county of Providence and anism for Looms; one. I do hereby declare that the iollowmg. is inn, cieor Mid exact description thereof, reference l had to the accompanying (llftX-Vliigs, or to the numerals of reference marked thereon, form 'a part of this specification.

This invention rels tes to looms, more perticulnrly to that class which are provide with automatic we[treplenishing mechanism for weaving, whereby afresh supply of filling is automatically transferred from the megazine to'the shuttle when the supply of filling has been exhausted or the thread broken, and is an improvement on my Patent No. 794,337, dated July 11, 199.3,

The object this invention is to provide improved mecimnism that wili give a. positive action to the rotating or nirweinent of the magazine.

A practical embodiment of the inventidn is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

In the drawings, Figure 1 represents transverse section of the loom, showing it suificient portion. to be understood with my i111 proved device attached thereto, showing the mechanism 01"" the automatic filling-replenishing apparatus in its normal position, section taken on line 1 1 of Fig. 2. Fig. 2 a front view of aportion of the loom, showing; my device attached thereto purtiully in section. Fig. 3 is a perspective view showing a detail of the hell-crank and the actuating lever that gives it a positive upward or feeding movement, also showii g the latch-bolt that prevents 21, rebound of said hclhcrsnk. is. showsjthe position of the cams and levers as it fresh bobbin is about to be struck into the shuttle. Fig. 5 represents an emerged view of the automatic iilliiigq'eplcnishiug apparittus'iu the position taken when. driving it bobbin into the shuttle. Referring to the drawings, st 1 is the loom breast-beu.m, and 2 2 the end frames, on

wvhich frames are set the ordinary loom-arch 3. At 5 is the rotatable magazine or fillingwhich l l. g l l l Patented. March 27, 1906.

feeder. Ail around the periphery oithis wheel are fixed spring-fingers 6, each pair of fingers being: especially designed and adapted 'i cog? re one end o cop or lilting-carrier and firmly supportut in a horizontal position while it being carried around under the foot of the plunger. This wheel 5 is mounted on and iixed to the shaft 4, which shaft is supported to turn in the hearing 6*, (see Fig. 2,) nearing being supported from the frame t This shaft extends out beyond the has mounted upon it the iillcop-vvheel and ing-cnd support '7 and the filling-end holder 8. The ratchet-wheel 9 is also mounted on and fixed to the shaft 4, so as to turn with it and the filling-carrying wheel. The teeth in this ratchet-wheel, are preferably made square and spaced to correspond to the spacing of the cup on the wheel 5, so that each time the -n'teliet is moved ahead one tooth a fresh bobbin brought in position to be struck dovm into the shuttle, as will he hereinafter described.

At 10 is hell-crnnlr iever mounted to turn freely on shaft 2, said lever having a horizontal arm 11 and. (2. depending arm 12. Go the end of arm 11 ore pivotally mounted. the two pcwls i3 and is on the pins 15 and 16. Fixed to the outer end of this arm are the fiat springs 17 and 18, that press on these pawls 13 and is, respectively, tohold them nor: mally into engagement with the teeth of the ratchet-wheel 9. 611 the pswl 14 is fixed a finger 19, that extends up and over the top edge at 20 of its supporting-arm 11. By pressing downward on this portion 20 of the finger the pawl 14; may be thrown out of engngement with the teeth of the rstchetwheel 9, and the arm 11, with its pawls, me then be carried downward for another toot into the position shown in Fig. 5 without turning the ratchet-wheel 9.

. in order to provide a positive action to the magazineieeding mechanism, the lever has been arranged to intercept the downward movement of the arm 11 of the bellcrank. This lever is pivoted to the bracket 27 of the l'rame at 61 and is connected at its opposite bell-crank arm 1 l to rotate the mag v WW n39 ezine. hen the l ell-crenk zirrn ii is reisec, the stop'scrcw 66 in its downwsrdly-e2;tending arm 12 by bringing up on the stop iits the upward movement of this hell crank arm 1] and the spring-actuated latch-bolt 67' enters the \l-shope slot 68 in the end. of the said arm 12 end prevei'its the some from rebounding when the hell crank arm. 1]. is moved quickly against the stop. The weight of the connecting rod 653 end hellwra-nk 68 normally holds the roll out of contact with the'revolving' actuatingmsni 64 until it is again required. to actuate the said rner'ihe m ism and feed the magazine. This little latch 67 is so shaped on its end thst it may he read ily withdrawn and not interfere with the backward movement of the bell-'crank-erm l 1 when the plunger-lever 25 descends.

The transfen'er comprises an arm or lever 25, pivoted in an arm 27 of bracket 24, said lever having a plunger-spindle 22 pivoted thereto at 2. Said spindleis provided with a plungenfoot 21 and is free to reciprocate in a bearing 23, pivotally supported st 2 3 in bracket 24, whereby the same 'is-free to edjust itself to the circular movement oithe up per end of the Spindle, To the opposite end of the lover at 28 is pivoted the'npright lever 29. The upper end of this letterlever extends up above the pivoting-point, forminga hook to which the spring 30 is attached. At 31 is the retchet-wheel-lockin pawl that is also pivoted to the bracket at 26. The outer end of this pawl is shaped to fit the square notches in the retchet' wheel and securely lock said wheel and the cop-wheel from mow ing in either direction while the filling is be 'ing driven into the shuttle. The opposite end of this pawl extends back o1 the pivo tingpoint at 32 and engages the under side of the longer-lever 25 by the turned-up end 33.

f desired, a screw 33 may be substituted for the upturned end (See Fig. 5.) This pawl is held up egainst said lever by the tension of spring 30, which spring serves the d'ouhis purpose of holding this pawl in position and also to exert a tension on the upper end of the upright lever 29 to swing its lower end into position for the purpose hereinafter specified.

At 33 is the ordinary weft-fork, mounted to slide in the usual way on the breast-beam, and at 341s the usual twoarm cannactuated lever that operates the fork when there is no weft-thread to raise its end out of the ath of said. reciprocating lever. One end oft e arm 35 engages the rear end of the fork-slide 35 and fixed at its opposite end to the shaft 26.

This shaft extends along under the breastbeam and'has the depending arm 37 fixed to its opposite end .At 38 is the crankshaft on. which is" mouhtcd the rotating com 39. Above this cam is located the canpber 40, which is held up and just out of en agement with said Chili by means of a-pivoteo latch 41 erase-e 4-0, rotates in the direction of the arrow the came-rin 40 is thrown quickly upward, carrying.
